Still, very few manufacturers make the rattrapante. Most notably watchmaker Richard Habring developed a way to add a split-seconds module onto a Valjoux 7750 years ago while working at IWC Habring now produces his own version under his own independent brand Habring². Just a handful of manufacturers make them in-house: we’re talking the likes of Patek Phillipe and A. Simply put, the rattrapante is very difficult to manufacture and exceedingly rare. In 2016, a Rolex 4113 split-second chronograph sold at Phillips for $2.3 million, setting a record for the most expensive Rolex ever sold at auction. In 1922, Patek Phillipe made the first rattrapante chronograph wristwatch, which in 1999 sold for over $1.9 million - at the time, the highest price for a wristwatch sold at auction. Nineteenth-century Swiss watchmaker Adolphe Nicole (who notably invented the chronograph reset function) is credited as the inventor of the rattrapante. The rattrapante chronograph is also sometimes referred to as a double chronograph or split-second chronograph. This allows the user to record multiple time intervals that start at the same time but do not end together (example: different lap times in a race).

Press that third pusher again and the stopped seconds hand catches up to the other seconds hand, which hasn’t stopped moving. When the extra pusher is depressed, the additional seconds hand stops. When you depress the pusher at two o’clock (as you would to start a standard chronograph), both seconds hands begin to spin the circumference of the dial in synchrony. The rattrapante, which roughly translates from French to “catch up,” is a chronograph movement with an additional seconds hand for the chronograph function superimposed over the normal seconds hand and an additional pusher.
